Hi there,
What is the messenger object? Why do you want its constructor to be called only once? Depending on what you need then you can choose the right event to initialize the object, or maybe both events are all your options. You can read more about this in ASP.NET Page Life Cycle Overview [^]
Btw, "urgently required help" is not a good subject at all, the title should be something that best describes your issue just in a few words.

Hello!
I have a big problem. Since three days I am searching for an answer without finding any functional hint.
I created a website with Visual Studio 2005 Professional. On the page I used the Login Control from Microsoft.
So far everything works fine on my Computer.
After uploading to my Windows 2003 Standard Server I only get the following Message:
An attempt to attach an auto-named database for file
c:\inetpub\wwwroot\Demo\App_Data\aspnetdb.mdf failed. A database with the same name exists, or
specified file cannot be opened, or it is located on UNC share.
I even installed Visual Web Developer Express Edition on my Sever and it works in the Debug Modus but not with my IIS 5.2.
Please tell me what I am doing wrong.
Thank you very much!!!
What I have done so far:
1) I installed SQL Server Express Edition on my Server.
2) I created a virtual directory.
3) I uploaded my complete website, including the App_Data directory.
4) A lot of things that did not help any further.

Ok I have set up a checklistbox and then an arrow button to move each selection over to the next listbox when asked - What I want is to allow the user to change the order of the displayed list. I need to reindex the second list box inthe order that they are sent over by the arrow button but can't figure out the syntax:
I have this:
lbOutcomes1.Items.Clear()
Dim chkListOutcomesItem As ListItem
Dim x As Integer = 1
For Each chkListOutcomesItem In chkListOutcomes.Items
If chkListOutcomesItem.Selected = True Then
Me.lbOutcomes1.Items.Add(chkListOutcomesItem.Text)
'Me.lbOutcomes1.SelectedIndex = x
End If
x = x + 1
Next
But it chokes on the commented out line - how do I accomplish what I am trying to do - I want the user to arrange the order of this sentences - this order will be saved back into my database and the table headers that will generated will appear int he order they selected. I need to figure this out ASAP as they want to roll out this sytem and I need to be able to allow column selection and moving them around.
Thx, Tammy

Hi, I use VS2003 asp.net 1.1 C#
I am working on bilingual website and I would like to use by exemple 2 files like career_fr.txt and career_en.txt that I will include in my html code based on the language. In html we use to write and works fine but when i want to switch the language it comes a problem for me.
I know that we can use .resx (ressource file) and that's what I do for short sentence or label. By using files.txt or files.inc that I can access based on language will be easier to edit for the non programmer.
Any suggestion will be wellcome.
Thanks for help,
Davy

IMHO, there are a couple of options that you may consider to include a text file in the ASP.NET:
+ Place a container such as Label, Literal ... controls in the web page, and dynamically load the text file based on the selected language and assign the content to the container.
+ Create a web user control and include it it the web page instead of the #include syntax.

Hi minhpc_bk,
Thanks for your suggestion.
Based on it I Resolved my problem with some little variances. I put a label on the web page and in C# side I created an object streamReader, I read my txt file and I assigned it to my label. In the C# code I switched between french and english based on what the user choose.
Thanks again

a . Based on the selection of a drop down I need to display
the corresponding panel in that table cell. Every thing works fine but
I see a lot of space in the table cell that was occupied by the other
panels though they are being hidden.
Can any one help me how to remove the space ? I dont' know how to use
style sheets or even do not if the the DIV functions works and how to
use it.
Here is a sample table code snippet with panels inside the table cells
for you to simple put some code to show me.

<asp:panel1>
<asp:panel2>
<asp:panel3>
<asp:panel4>

Learn how to use style sheets and divs. You already knew the answer!

Didn't get an immediate answer to your previous question?
Changing the title and reposting I'm sure will definately get a better response.
only two letters away from being an asset

maybe you could remove the title header.
something like
Request.RemoveHeader()
then
Request.AddHeader()
in 2.0 this is easily accessed on the Page so this is just a guess

1 line of code equals many bugs. So don't write any!!

Hi all,
I hope you can help me with the following problem...
A custom control I've created will not perform 2-way databinding on one of its properties in a FormView control - when inserting (or editing), the control's property value is not retrieved but I know the property has a value and is stored in the viewstate.
The custom control is a composite control (Inherited from System.Web.UI.WebControls.CompositeControl) which is used in the Edit and Insert ItemTemplates of a FormView control.
I've databound a property (DataValue) of the control like this:
<cc1:custCtrlTest1 id="SiteId" runat="server" DataValue='<%# Bind("siteId") %>' ></cc1:custCtrlTest1>
The property declaration in the custom control is like this:
< _
Bindable(True), _
Category("Appearance"), _
Description("Value to display in the valueTextbox.") _
> _
Public Property DataValue() As String
Get
EnsureChildControls()
Return valueTextBox.Value
End Get
Set(ByVal value As String)
EnsureChildControls()
valueTextBox.Value = value
End Set
End Property
During the iteminserted or iteminserting events e.Values.Item("siteId") is empty.
Strangely, in the ItemTemplate the control works fine, a value is databound and given to the DataValue property, it's only failing when binding in the other direction.
Can anyone help?
Thanks,
M@

You may try with Bindable(True, BindingDirection.TwoWay)

Thanks for the suggestion, I've made this change
minhpc_bk wrote: Bindable(True, BindingDirection.TwoWay)
to the bindable property attribute and the bindable class attribute in my custom control - but unfortunately it's not done the trick.
Any other ideas would be greatly appreciated!
Thanks,

Perhaps the problem might be somewhere else either in the control or in the way you use the control in the testing web page. Below is a quick example:
[DefaultProperty("DataValue")]
[ToolboxData("<{0}:CustCtrlTest runat=server></{0}:CustCtrlTest>")]
public class CustCtrlTest : CompositeControl
{
TextBox valueTextBox;
[Bindable(true)]
[Category("Appearance")]
[DefaultValue("")]
[Localizable(true)]
public string DataValue
{
get
{
EnsureChildControls();
return valueTextBox.Text;
}
set
{
EnsureChildControls();
valueTextBox.Text = value;
}
}
protected override void CreateChildControls()
{
Controls.Clear();
CreateControlHierarchy();
ClearChildViewState();
}
protected virtual void CreateControlHierarchy()
{
valueTextBox = new TextBox();
valueTextBox.ID = "valueTextBox";
Controls.Add(valueTextBox);
}
}

I think the problem must have been on my test web page as you suggested.
I've just re-created the test page from scratch and now it's working fine! Although I can't see any code differences from the last time I created the page, could it have been the order in which I built the page in Visual Studio maybe??
Anyway, along with the bindable changes to the control and a page rebuild all is now well! 
Thanks for the help!
